Substitute Part Grouping Explanation

Substitution of the LP3996SD-3308/NOPB is determined by the following critical parameters:

Dual-output configuration with fixed positive voltage regulation
Output current capability of 150mA and 300mA per channel
Maximum input voltage tolerance (6V for main part)
Dropout voltage performance at specified current levels
Surface mount package compatibility (10-pin WFDFN/MLF form factor)
Operating temperature range (-40°C to 85°C minimum)
Control features including enable functionality
Protection features for over-temperature and short-circuit conditions

Engineering Selection Recommendations

The LP3996SD-3308/NOPB is obsolete and no longer available from Texas Instruments. The MIC2212 series from Microchip Technology provides direct functional equivalents with active product status and extended lifecycle support.

All MIC2212 substitute parts maintain dual-regulator architecture with 150mA and 300mA output capability in compatible 10-pin surface mount packages. The MIC2212 series offers improved specifications including lower quiescent current (80 µA versus 100 µA), extended operating temperature range (-40°C to 125°C versus -85°C), and enhanced protection features with over-current detection.

Selection among MIC2212 variants depends on required output voltage combinations. The primary difference between substitutes is the fixed output voltage pairing. All variants are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

The maximum input voltage for MIC2212 parts is 5.5V, which is lower than the LP3996SD-3308/NOPB specification of 6V. Applications requiring input voltages above 5.5V require circuit redesign or alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can MIC2212 parts directly replace the LP3996SD-3308/NOPB without PCB modifications?

A: MIC2212 parts are pin-compatible with the LP3996SD-3308/NOPB in the 10-pin WFDFN/MLF package. However, the output voltage configurations differ. The LP3996SD-3308/NOPB provides 3.3V and 0.8V outputs, while MIC2212 variants offer different fixed voltage pairings. Select the MIC2212 variant matching your required output voltages. No PCB layout changes are required for compatible voltage combinations.

Q: What is the impact of the 5.5V maximum input voltage on MIC2212 parts versus the 6V specification of the LP3996SD-3308/NOPB?

A: The MIC2212 series has a maximum input voltage rating of 5.5V compared to 6V for the LP3996SD-3308/NOPB. Applications operating at input voltages between 5.5V and 6V cannot use MIC2212 substitutes without circuit modification. Verify your input voltage range before selecting a substitute part.

Q: Are there differences in dropout voltage performance between the LP3996SD-3308/NOPB and MIC2212 substitutes?

A: Dropout voltage specifications differ between the main part and substitutes. The LP3996SD-3308/NOPB specifies 0.22V at 150mA and 0.55V at 150mA. MIC2212 parts specify 0.25V at 150mA and 0.42V at 300mA. These differences may affect minimum input voltage requirements in your application. Evaluate dropout voltage performance for your specific operating conditions.

Q: Which MIC2212 variant should I select for my application?

A: MIC2212 variants differ only in fixed output voltage combinations. Select the variant providing the output voltages required by your circuit. Available combinations are: 1.8V/3.3V (MIC2212-GSYML-TR), 2.5V/3.3V (MIC2212-JSYML-TR), 3.3V/1.8V (MIC2212-SGYML-TR), 3.3V/2.5V (MIC2212-SJYML-TR), 3.3V/2.8V (MIC2212-SMYML-TR), and 1.6V/3.3V (MIC2212-WSYML-TR).

Q: What are the advantages of MIC2212 parts over the obsolete LP3996SD-3308/NOPB?

A: MIC2212 parts offer active product status with ongoing manufacturer support and availability. They provide lower quiescent current consumption (80 µA versus 100 µA), extended operating temperature range to 125°C, and enhanced protection features including over-current detection. These improvements support modern design requirements and extended product lifecycles.

Q: Are all MIC2212 variants available in Tape & Reel packaging?

A: All MIC2212 substitute parts listed are available in Tape & Reel (TR) packaging, suitable for automated assembly processes. Inventory levels vary by variant, with MIC2212-JSYML-TR offering the highest stock availability at 4594 pieces.
